WMD/SSF Pole Zero

POLE-ZERO is a 4-pole (24dB/octave) low pass Voltage Controlled Filter (VCF) utilizing MOSFET transistors. MOSFETs are known for their soft, vacuum tube like distortion when overdriven.
POLE-ZERO is designed to exploit these characteristics with the addition of a MOSFET saturation control and provide a much wider palette of sounds when compared to a standard VCF.
A Voltage Controlled Amplifer (VCA) is also a relatively novel addition and provides a simple way to amplitude modulate the filter without the need of an external VCA.
Power Draw: +20mA, -20mA. 6HP width. 25mm Depth.
